APC by Schneider Electric AR3105W NetShelter SX 45U Free-Standing Rack Enclosure
Overview
The APC by Schneider Electric AR3105W is a 45U free-standing rack enclosure in the NetShelter SX line, finished in white and built to house network, security, and IT equipment in environments where a standard black finish doesn't meet aesthetic or facility requirements. At 600mm wide and 1070mm deep, the AR3105W provides the internal clearance needed to accommodate full-depth servers, network switches, patch panels, and surveillance NVRs without forcing cable routing compromises. The white colorway is the primary differentiator from the otherwise identical black NetShelter SX siblings — relevant in healthcare, education, and clean-room adjacent deployments where rack color is specified by facilities teams.
Key Features
- 45U Capacity: 45 rack units of usable vertical space gives you room to fully populate a dense security or IT stack — NVRs, PoE switches, patch panels, UPS units — without needing a second enclosure on day one. That reduces floor footprint and simplifies cable plant management.
- 600mm Width: The 600mm internal width is the standard EIA-310 19-inch rack width. Every standard 1U through full-chassis device mounts without adapters. Wider than a 19-inch rack dimension matters for side clearance — verify your aisle width if deploying in a tight IDF closet.
- 1070mm Depth: 1070mm of internal depth accommodates full-depth 1U servers and high-density patch configurations. Shallow devices (switches, NVRs, 1U appliances) leave room for structured rear cable management without bending cables at the connectors.
- Free-Standing Design: No wall anchoring required. The AR3105W stands independently, which simplifies placement in finished spaces and allows repositioning without structural modifications — useful during phased buildouts or tenant improvement projects where wall penetrations are restricted.
- White Finish: The white powder-coat finish is the specification difference from the standard-black AR3105 variant. Facilities-driven deployments — hospital corridors, education wings, retail back-of-house — often specify white infrastructure to match interior standards. Confirm your project spec sheet before ordering; black equivalents are available if the color requirement doesn't apply.
Integration and Compatibility
The AR3105W accepts standard 19-inch EIA-310 rack-mount equipment across the full 45U height. It is compatible with APC UPS systems and power distribution units designed for the NetShelter SX line, as well as third-party PDUs, blanking panels, and cable management accessories built to the 600mm-wide rack standard. For network video recorders, PoE switches, and access control servers that form the backbone of a physical security infrastructure, the 1070mm depth clears virtually all 1U and 2U appliances without modification. Pair with a rack PDU sized for your total load and a cable management solution to complete the installation. Review the APC by Schneider Electric enclosure line for side panel, door-lock, and caster kit options that integrate with the NetShelter SX platform.
Frequently Asked Questions
Q: What is the difference between the AR3105W and the AR3105?
A: The AR3105W is the white-finish version of the NetShelter SX 45U 600mm x 1070mm enclosure. The AR3105 is the identical unit in standard black. Both share the same 45U capacity, 600mm width, and 1070mm depth. Choose the AR3105W when your facility specification or aesthetic requirement calls for white infrastructure.
Q: Is the AR3105W compatible with standard 19-inch rack equipment?
A: Yes. The AR3105W conforms to EIA-310 19-inch rack standards. Any device with standard rack ears mounts without adapters across the full 45U height.
Q: Can the AR3105W be used for physical security infrastructure such as NVRs and PoE switches?
A: Yes. The 1070mm depth and 45U capacity make it suitable for security head-end equipment including NVRs, managed PoE switches, access control servers, and patch panels. The free-standing design does not require wall attachment, which is practical in finished IDF spaces.
Q: Does the AR3105W ship with side panels and a door?
A: Package contents are not confirmed in available specifications. Verify included accessories with your order confirmation or the manufacturer's current product listing before deployment planning.
Q: Is the AR3105W available in configurations other than 45U?
A: The NetShelter SX line includes multiple rack unit sizes. The AR3105W specifically is the 45U variant in white. Other U-heights and depths are available as separate models within the NetShelter SX family.
The spec that drives most AR3105W selections isn't the 45U height or the 1070mm depth — it's the white finish. In my experience deploying security head-end infrastructure in healthcare and education facilities, the rack color is frequently called out on the facilities spec sheet, and showing up with a black enclosure in a white-specified IDF closet creates a change-order conversation nobody wants. The AR3105W closes that gap cleanly.
Technical Highlights:
- 45U Vertical Capacity: Enough space to fully populate a security head-end — NVR stack, managed PoE switching, access control server, patch panel, and a rack-mount UPS — without a second enclosure. That matters when floor space is constrained in a finished IDF room.
- 1070mm Depth: Clears full-depth 1U and 2U appliances with room left for rear cable management. Shallow NVRs and switches leave generous rear clearance, which means you're not fighting bent patch cables six months post-install.
- 600mm Width: Standard EIA-310 19-inch compatibility — no adapters, no custom brackets. Every vendor's rack-mount security appliance slides straight in.
Deployment Considerations:
- Free-standing installation means no wall anchoring, which is an advantage in tenant improvement and leased-space deployments where penetrations require landlord sign-off. Verify floor leveling before final equipment population — an unlevel rack stresses door alignment on fully loaded enclosures.
- Weight capacity, included hardware (side panels, door locks, casters), and thermal/airflow ratings are not confirmed in available specifications — request the manufacturer's current datasheet before finalizing load calculations for dense security deployments.
The AR3105W is the right call for healthcare, education, or retail environments where a white rack enclosure is a facilities requirement, not a preference — and where the standard 45U NetShelter SX platform is already the specified enclosure line.
